Swine Influenza—or "swine flu"—is a respiratory disease of pigs caused by type A influenza virus. Regular outbreaks of swine flu in pigs occur each year. Swine flu outbreaks infect large numbers of pigs but the death rate is low. Swine flu viruses circulate among the world's pig population throughout the year, but most outbreaks occur during the late fall and winter months. The swine flu virus (an influenza type A H1N1 virus) was first isolated from a pig in1930.
There are presently four main influenza type A virus subtypes affecting pigs: H1N1, H1N2, H3N2, and H3N1. Most of the recently isolated flu viruses from pigs have been H1N1viruses.
Influenza viruses can be directly transmitted from pigs to people and from people to pigs. Humans do NOT get swine flu from eating pork. Pigs frequently contract human flu. They are also susceptible to avian flu. Swine flu can spread to humans who are in close proximity to infected pigs (and vice versa), such as in pig barns and livestock exhibits housing pigs at fairs. Human-to-human transmission of swine flu has been infrequent. When it occurs it is transmitted in the same way seasonal flu spreads in people. Person-to-person transmission of the flu usually happens through coughing or sneezing of people infected with the influenza virus. People may become infected by touching something with flu viruses on it and then touching their mouth or nose. People are contagious from about a day before they have symptoms to seven days after the onset of a flu.
In March and April 2009, more than 1,000 cases of swine flu in humans were detected in Mexico,and more than 80 deaths are suspected to have a connection with the virus. As of April 26, 2009 there were 20 laboratory confirmed cases in the United States and a public health emergency was declared. The Center for Disease Control is carefully investigating the outbreak in humans and documenting changes at this link.

First of all thanks a lot for the useful information about swine flu. I think that all people should know the basic information about this dangerous disease and it is an essential thing if we want to be healthy. I think that all know that more and more people are dying from this virus so it is really important to follow all doctor's advices indeed. Well I have heard that some swine flu symptoms are very similar like stomach virus symptoms , is it true? I will definitely try to find more information about this flu in your website. Personally I think that the best what we can do is to avoid public places and use swine flu masks. Thanks a lot one more time for the useful entry and I will be waiting for more information about this flu.
Now when all this epidemic had slow down I can definitely say that it was a little bit exaggerated. The mortality rate was not too high and there was no reason to make such a panic in the society. Simple flu mortality rate is even bigger. All these vaccinations against flu are dangerous too. I think that many of you have heard that they are full of mercury. And it is not good at all. This chemical is very dangerous and can have some serious consequences. Moreover it can interact with various medications such as Cialis, Levitra or others. That's why you must be careful taking it. I would say that it is better to avoid h1n1 vaccine than use it. However it is only my own opinion. Thanks for the interesting and informative article by the way.
Swine Flu is caused by H1N1 virus & the carrier for this are pigs. So beware of them. Try to avoid pork for some time. They are injurious & can be infective. Now the vaccine for swine flu are also available. So one can be prevented from this.

There is a famous proverb "Health is above wealth". Nobody would deny the importance of its meaning. Some factors that can cause wrinkles: Sun's UV rays - Too much exposure to the sun can cause wrinkles and sun spots. Smoking - Smoking has a negative effect on the skin. It affects its ability to repair its self from damage. Stress - Stess can affect the well being of a person.This is exactly why it is so important to only choose collagen creams that are made with all natural and organic ingredients. Good creams make face healthy. Reality is, it is indeed a part of everyone's life. We will all age. Just because aging if part of the natural order of things does not mean we must accept what the years (and exposure to the environment) have done to us. You can dwell on different ideas about it, which I may not know but as much as possible, I would want to continue maintaining a young image
